Star Wars Jedi Knight: Jedi Academy is a Star Wars first- and third-person action game released in September 2003. It was developed by Raven Software and published, distributed and marketed by LucasArts in North America and by Activision in the rest of the world.
The game is powered by the same version of the Quake III: Team Arena engine used in its predecessor, Star Wars Jedi Knight II: Jedi Outcast, containing Jedi Knight II's modifications to the Quake code to include lightsaber combat. The player can modify the character's gender and appearance, and can construct a lightsaber by choosing the hilt style and blade color. After completing certain objectives, different saber and combat styles become available.
This is the best star wars game out there. Unlike most games, it uses a physics based lightsaber like jedi outcast bu improved. Depending on the strike that you do and how the player is hit changes the out come of the entire battle.

The errors you are seeing I believe are due to OpenGL issues. I was able to fix these issues by downloading a file called atioglxx.dll and put it directly into my gamedata folder. I believe if you have nvidia you need a different one. I don't remember exactly where I found this. Try googling for it.
